Patented Aug. 11, 1925o :an ST ALFRED J. RUDOLPH,OFPHILADELPHA,IEFENNSYLVANIAL Application `11ct1-T111yv25,y 1921. S'elialjNO.487,248,"

5.' delphia and State of Pennsylvania, have invented an Improvement inSoil-Pipe Connections, of which the following is a speciication.

My invention relates to improvements in n soil 1i ipeconnectionsand ithas for one vot its objects to provide means whereby angular adjustmentsbetween the upper end portions ot a soil pipe and a bowl or hopper maybe effected without` in any way altering 1 or rearranging. the structureof the c0nnection.

A further object of my invention isto provide ahopper-flange, which issecured tothe lower end of a bowl or hopper, having a. projectingannular portion, the external surface ot'which isspherical constituting'the zone otasphere and therefore adapted to have continuous or unbrokencontact with the interior surface of a cylindrical tubular member intowhich it may be projected even though the axes of the said annularportion and of the said tubular member may not be 1n, alinement. Y

At stilli further object is to provide meansV whereby` a verticallypositioned bowly or. hoppen which is supported on an inclined Hoor orother support may be readily con@ nectedwith the soil pipe.

@ther objects andr advantages of my in vention will be pointed out inthe detailed description thereof: which follows or will7 beapparentlfrom such description.

In order that the invention may be 'more readily understood and itspractical advantages 'fully appreciated reference may be had-to theaccompanying drawing in which isV shown one form ot' embodiment thereof.However, it will be understood that the invention is susceptible ofembodiment in other `forms of construction than that shown and thatchanges in the details of construction -may be made within the scope oftheclaims without departing from the said. invention.

In the drawing:

Fig. l is a centralverticalsection `ot-the lower and upperportionsrespectively, ot a bowl: or'hopper and av soil pipe andof' the meansembodying my inventionv for connecting: the same;

- Fig. Qis a similar view showingthe parts in slightly vdifferentposition or relation with respect to each other. from what they areshownin Figui; and' I I F 3 is a transverse horizontal' sectional view takenon` the line 3;-3 ot'Fig, l.

Referringk tok the drawing: l` designates the lowerv or' neck portionof" a waterfcloset hopper or bowl having the laterally extending flangeQat the lower end thereot V`The' under sideot' this flange aroundltheopening oi the neck portionot the bowl or hopper'is. cut away, asindicated at 3, so as to leave a depending' inclosingportion t' whichsur;

rounds and conceals the outer edgesofthe' flanges constituting` portionsof' the means tor connecting the bowl or. hopper to the' upper endportion of a soil pipe 5.

Secured to-the lower end ot the bowl or hopper lis amember S'which'maybedesignated as a hopper-flange. rlhe upper'end portion ot this memberprojects upwardly a short' distance into .the lower end of the bowl orhopper, andthe interior diameter ot the said member is ythe same as thatofthe portion l ot said bowl or-hopper. AIt will be notedthat at its.lowerjend the interior ot'the opening oi' the bowl or hopper is flared'outwardly as indicated at 9, and that` the outer surface off theupper'portion'y of the, vmember 8 is inclined downwardly andY outwardly,as'indicated at 10, so that the two surfaces nt` together'to form avsmooth joint between the upper`- edge ofVv the mem* ber S and the'adjacent interior surface of the portionv tot the hopper or bowl?l ThelowerportionA of the member 8 projects a distance belowthe lowerfendofthe hopper, as indicated at l1, andthe-exterior surface thereof isspherical, as indicated at l2, the saidE surface constituting the zoneof1 a sphere. At about the middle of the tubular portion of the'member 8a laterally extending annular flange liis provided which is adaptedto'itclosely against'the under side ot the lowerend portionof thebowlorhopv per within the cut out; portion 31 thereof. The said iiange lis provided with` projec tions- 16, dia'm'etrically4 situatedl withrespect to each other, the outer endsl otwhichare provided with screwthreaded openings 17 with which thescrew threaded endsiot. tubular bolts18 are adapted to be engaged for aidingin holding andpsecuri'ng themember 8l in position upon the ,lowerl end of the bowl or hopper. Thetubular bolts 18 extend through holes 19 in the flange 2 of the bowl orhopper.

The said member 8 is permanently secured to the bowl or hopper by meansof a suitable cementitious material, such as litharge, a thin layer ofwhich is placed in between the inclined surface 9 of the said member andthe upper surfaces of the flange 15 and the projections 16 and theopposing surfaces of the adjacent portions of the bowl or hopper. Forco-operating with the member 8 I have provided a cylindrical tubularmember 20 having a laterally and outwardly extending fiange 21 at itsupper edge, which flange is provided with projections 22 similar to theprojections 16 previously referred to, and which projections 22 arelocated underneath the projections 16, as is clearly shown in Figs. 1and 2 of the drawing. The projections 22 are provided with screwthreaded openings 23 with which the lower screw threaded ends of bolts24 are adapted to be engaged. rlhese bolts 211 extend upwardly throughthe tubular bolts 18 and the upper screw threaded ends thereof areengaged by nuts 25.

The radius of the exterior spherical surface 12 of the member 8 is equalto the radius of the interior surface of the tubular flanged member 20,so that when the end portion 11 of the member 8 is extended into thesaid member 2O the said spherical surface 12 contacts with the interiorsurface of the member 2O along a continuous circular' line. The member2O projects downwardly into the said upper end portion of the soil pipe5 and the exterior diameter thereof is considerably less than theinternal diameter of the said soil pipe. The lower end of the member 20is flared outwardly, as indicated at 30, so as to cause contact orpractical contact of the lower outer edge thereof with the inner surfaceof the upper end portion of the soil pipe 5. It will be seen that thereis thus provided a chamber for the reception of packing comprising aportion 31 of suitable librous material and a portion 32 consisting oflead or other suitable metallic packing material. lThe packing materialis inserted and packed into the chamber bctween the exterior surface ofthe member 2O and the opposing interior surface of the upper end portionof the soil pipe 5 in known manner.

The floor upon which the hopper is situated lis indicated at 35 and isprovided with an opening 36 into which the upper end portion of the soilpipe 5 projects, as is shown in the drawing.

In Fig. 1 the floor 35 is shown in a horizontal position, whereas inFig. 2 the floor is slightlyV inclined. It is necessary, however, thatthe bowl or hopper shall be supported in a vertical position. lt is tomeet such a situation that my invention, comprising the projectingportion 11 of the hopperflange member 8 having a spherical outer surfaceas described, is particularly well adapted.

The upper end portion of the soil pipe 5 entering the opening 3G througha floor 35 which is inclined is likely to be and usually is somewhatinclined so that its axis does not extend vertically. The flange 21 andthe projections 22 are situated against the floor and are thereforeinclined from a horizontal plane corresponding to the inclination of thefloor surface. It follows, therefore, that the lower surfaces of theflange 15 and of the projections 16, which occupy a horizontal plane,would contact with the upper surfaces of the corresponding portions ofthe tubular flanged member 2O at certain points'or at one side only, thespace between the opposing surfaces of said portions being wedge shaped,as is indicated at 27 in Fig. 2. The space between the lower edge of thedepending portion 4. of the flange 2 which is elevated a distance abovethe floor is filled with a suitable plastic material, as indicated at37.

It will be seen that I have provided a construction of connection whichis adapted to form a water-tight joint between the bowl or hopper andthe adjacent upper end of a soil pipe regardless of whether the axes ofthese portions are in alinement or whether such axes are angularlyrelated to each other. It will be further seen that such construction isvery desirable in view of the fact that it frequently becomes necessaryto make connections between bowls or hoppers and soil pipes throughfloors which do not occupy horizontal positions, but which, on thecontrary, are inclined with respect to a hori- Zontal plane.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A soil pipe connection, comprising a hopper-flangemember secured to the lower end of a bowl or hopper, the said flangemember being provided with a portion projecting below the plane of theflange, said portion being adapted to project into the upper end of acylindrical tubular member and being provided with a spherical exteriorsurface, the radius of which is equal to the radius of the interiordiameter of the said tubular member.

2. A soil pipe connection, comprising a hopper-flange member including atubular portion and a laterally and outwardly extending flange extendingfrom about the middle of the said tubular portion, the exterior surfaceof the portion of said member above the said flange being inclinedoutwardly and the exterior surface of the portion of said tubular memberbelow the said flange being spherical, and a cylindrical tubular memberinto which the last named portion projects, the radius of the interiorsurface of the said tubular member being equal to the radius of the saidspherical surface.

3. In combination, a water-closet hopp'er or bowl, a hopper-flangemember having portions extending in opposite directions from anoutwardly extending flange, the portion upon one side of the said flangeprojecting into the lower end of the said hopper or bowl, and theportion upon the opposite side of the said flange having a sphericalexterior surface, and a cylindrical tubular member into which the saidlast mentioned portion is adapted to project and with the interiorsurface of which the said exterior spherical surface is adapted tocontact along a circular line, substantially as described.

In combination, a water-closet hopper or bowl, the interior surfaceof the lower end of which is flared outwardly, a hopperflange memberhaving one end portion projecting into and fitting the flared interiorportion of the said hopper or bowl and having a downwardly projectingportion provided with an exterior spherical surface, a soil pipe, acylindrical tubular flanged member co-operating with the saidhopper-flange member and projecting into the upper end portion of thesaid soil pipe, and the downwardly projecting portion of the Saidhopper-flange projecting into the said tubular flanged member, theradius of the interior surface of the said tubular flanged member beingequal to the radius f the spherical exterior surface of the saiddownwardly projecting portion, and means for securing the saidhopper-fiange member and the said tubular flanged member to the saidbowl or hopper.

z5. In combination, a water-closet bowl having an annular projectionextending from its lower end, the exterior surface of which projectionis spherical, a soil pipe, and a cylindrical tubular member connectedwith said bowl and extending into said pipe and the said projectionextending into said tubular member and contacting therewith, the radiusof the said spherical surface being equal to the radius of the inte-riorsurface of said cylindrical tubular member.

6. In combination, a water-closet bowl, a hopperflange permanetlysecured to the lower end of the said bowl and having a downwardlyprojecting annular portion the exterior surface of which is spherical, acylindrical tubular member into which said downwardly projecting annularportion extends and with which it contacts along a circular line, meansfor securing said tubular member to said bowl, a soil pipe into whichsaid tubular member extends, and means for securing said tubular memberto said soil pipe.

In testimony that I claim the foregoing as my invention, I have hereuntosubscribed my name this 19th day of July, 1921.
